Guichenotia seorsiflora is a species of flowering plant in the family Malvaceae and is endemic to the south-west of Western Australia. It is a low, spreading, multi-stemmed shrub with linear to narrowly egg-shaped leaves and white flowers arranged singly in upper leaf axils.

Description

[edit]

Guichenotia seorsiflora is a spreading, multistemmed shrub that typically grows to 30–45 cm (12–18 in) high and 30–55 cm (12–22 in) wide, its new growth covered with white, star-shaped hairs. Its leaves are linear to narrowly egg-shaped, 8–20 mm (0.31–0.79 in) long and 1–2 mm (0.039–0.079 in) wide on a petiole 1–2 mm (0.039–0.079 in) long with linear to narrowly egg-shaped stipules two-thirds as long as the leaves, at the base. The edges of the leaves are rolled under, and the upper surface is covered with white, star-shaped hairs. The flowers are arranged singly in upper leaf axils with a bract 3–4 mm (0.12–0.16 in) long at the base, the pedicel 12–18 mm (0.47–0.71 in) long, with a bracteoles 1–4 mm (0.039–0.157 in) long at the base, on a peduncle 10–25 mm (0.39–0.98 in) long. The petal-like sepals are pink in the bud stage, later white, joined at the base and covered with white, star-shaped hairs. There are tiny, dark red petals but no staminodes. Flowering occurs from July to September.[2][3]

Taxonomy and naming

[edit]

Guichenotia seorsiflora was first formally described in 2003 by Carolyn F. Wilkins and the description was published in Australian Systematic Botany.[4] The specific epithet (seorsiflora) means "separate-flowered", referring to the flowers arranged singly.[3][5]

Distribution and habitat

[edit]

This species of guichenotia usually grows on breakaways in heath and open woodland in scattered locations near Youndegin, Corrigin and Kellerberrin in the Avon Wheatbelt bioregion in the south-west of Western Australia.[3][2]

Conservation status

[edit]

Guichenotia seorsiflora is listed as "Threatened" by the Western Australian Government Department of Biodiversity, Conservation and Attractions,[2] meaning that it is in danger of extinction.[6]
